Calibre(64-bit) is program to manage your eBook collection.

What is new in this release:

Copy to library: Add an action to show a dialog that allows for easy selection of libraries for copy/move. Useful when there are a large number of libraries to choose from.

Server: Allow deleting a downloaded book from the "Browse all downloaded books" screen

Bug fixes:

Hopefully fix an issue with the book list jumping around when using the mouse on some computers

E-book viewer: Change the default fonts on windows to the Liberation font family. This matches the other platforms and avoids rendering issues with Times New Roman.

Fix editing the authors via the book list not respecting the tweak to control author name splitting

E-book viewer: Fix external links not working in the footnote popup panel

Fix a regression that broke command line completion in bash

Improved news sources

What is new in version 2.9:

New Features

E-book viewer: Show footnotes in a separate popup window

Now when you click on a link to a footnote/endnote, the corresponding note is shown in a separate popup window, for convenient reference. Footnote links are recognized using the EPUB 3 footnote markup as well as some heuristics. Any superscript or subscript links are assumed to be footnote links. Any link that links to another file which in turn links back to the original link, is assumed to be an endnote.

Cover Grid: Improve scroll wheel based scrolling.

On windows and linux a single "tick" of the wheel now scrolls by about half a row instead of a full screen. On OS X, scrolling is pixel based, so as you scroll faster, more content is scrolled.

Get Books: Add the Bubok Portugal store

Performance improvement for large libraries that using custom columns built with templates

Improved news sources

Boston Globe

Brand Eins

What is new in version 2.7:

New Features

Support for the new Kindle Voyage

The notification for the completion of background jobs, such as bulk metadata download, has been redesigned to not interrupt your work. It now waits in the lower right corner of the main window until you are ready to deal with it

Insert metadata as jacket page: Make the invisible tags used for searching across books format better, by giving them their own table row.

Book details panel: Show custom column values for numeric columns even when the value is zero

Allow clearing of date and number type fields by right clicking and choosing clear when editing the fields in the book list or edit metadata dialog

Bug Fixes
